Dendrochronology and treeline dynamics within arctic and alpine localities in western and central Canada
DownloadFall 2012
The transition from forest to tundra, commonly called treeline, is expected to advance, particularly in northern latitudes. Treeline in two subarctic locales: the western Mackenzie Mountains, Northwest Territories, and the western Hudson Bay Lowlands southeast of Churchill, Manitoba were studied,...

Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...

Social-ecological reclamation in the Northwest Territories: A framework for healing human-caribou relations
DownloadFall 2018
The impacts of mining activity on human-caribou relationships in the Northwest Territories have been a focus of study in both the natural and social sciences for decades. Guided by Łutsel K’e Dene First Nation elders and harvesters, this study used dendrochronology methods and best practices for...

Spatial and temporal stand dynamics of mature lodgepole pine forests of the Canadian Rocky Mountains
DownloadFall 2015
In forest ecosystems, structure and species composition change over time as a function of ageing and minor disturbances and it is important to understand these changes for predicting forest productivity and habitat suitability for other plant and animal biota. Disturbances play a major role in...

Through they Eyes of a Tree: Monitoring Environmental Change Using Stable Isotope Dendrochemistry
DownloadSpring 2013
Stable isotope dendrochemistry of needles, twigs, and tree rings were used to identify the impacts of a changing global atmosphere in two separate environments with different anthropogenic loads: the boreal forest surrounding the Athabasca Oil Sands region (AOSR), Alberta, Canada, subject to a...

Tree population responses to extreme climate events to guide reforestation under climate change
DownloadSpring 2018
As climates warm and extreme climatic events occur with more frequency and severity, maintaining forest health and productivity may involve planting seed sources from warmer, drier areas. To guide such reforestation strategies, this work analyzes the risks of both climate change and assisted...
